Vicinal bisheterocyclizations of alkynes via nucleophilic interception of a catalytic platinum carbene
Allegretti, Paul A.,Ferreira, Eric M.
, p. 17266 - 17269 (2013)
A novel platinum-catalyzed double heterocyclization of propargylic ethers is described. The transformation exploits the intermediacy of a key α,β-unsaturated carbene. The reactivity of this carbene is such that systems can be developed which avoid a complicating 1,2-hydrogen migration, allowing remarkable versatility in the selective syntheses of oxygen- and nitrogen-containing vicinal bis-heterocyclic compounds.
